To all 'whom #may concern.'

Be it known that I, FREDERICK, STRATTNER OREM, a ncitizen of the United States, re-

' siding at Baltimore, Maryland, have invent" engines, designed asia choke or stop for all f impurities in the air supply thereof.

Ypistons and .ing oil and Such engines, as used for motor vehicles and the like are constantly inspiring along with the air necessary to combine with the gasolene to form the combustible mixture,

' considerable quantities of fine dirt or dust and at times more or less moisture.

Much lof this ne dirt or dust, coming from the surface of al Macadam road is of a very hard or gritty nature. l l

A portion of the dirt and dust combines with the lubricating oil and becomes de-l positedvon the walls of the combustion chamber, spark plugs and piston heads, while a part indsits way into the cylinders where it causes rapid wear between piston rings, cylinders and nally reaches the where it mixes with the lubricatwith this oil bathes or lubricates all the interior andmoving parts, including crank and rod bearingsand also gears.. It

crank case l is evident that this grinding which takes f and and fine Macadam vin great wear and rapid place between the metal dirt will soon result v deterioration of .the motor.

In devising my present invention I have aimed to provide an extremely simp el and economical device adaptable to any or inary internal combustion engine which will effectually prevent such impurities as above referred to from reaching the interior of the The invention includes the novel features of construction and4 arrangement and combination of parts as defined by the appended claims, an embodiment of the invention being hereinafter-described in connection with the accompanying drawings, in which;

Figure is a side elevation showing a manifold intake'pipe and carbureter of conventional form with `my attachment applied thereto. Y ""1 Fig. 2 is a plan vieweoff the attachment,

Referring by reference characters to this drawing, theinumeral l designates the lower portion of the pipe of the intake manifold offan internal combustion engine and 2lthe lntake indicated at 3. To this air intake attachment which comprises an approxij mately dish-shaped memb/er having a depending tubular portion 4: designed to be connected to the air intake of the carbureter formica.

cc carbureter thereof having an upturned air I secure my improved in any suitable manner, as by inter-engaging threads las shown. i

To the peripheral edge of this dish-shapedmember I secure the medium for eliminating from the air the impurities referred to.\-

Such medium is shown as a' diaphragm 5 which must be of such nature as to be practically impervious to air when the motor is'not runnlng, but which, when the engine is in action will, under the suction thereof, permit the passage of'all they air necessary to form thevcombustible mixture. he diaphragm may be composed of pressed material having the fibers closely associated, or it may be aclosely but I have found feltk to be a material well adapted for the purpose.

In order that ample 4air may pass through the iaphragm when theI engine is running it is'necessary that the diaphragm should have a much larger area than the interior j cross section of the intake of the carbureter, and I have found that the relative proportions of'forty to one give excellent results.

woven textile fabric,

` An advantageous manner of'securing the i by bolts portion of the diaphragm is Abolt being secured tothe spiders by washers and lock nuts as indicated at 8 and 8.

I have found by practical demonstration that an attachment such as above described so eliminates all foreign ties and moisture from .the air passing to the engine that the life of the m'otor is greatly prolonged and trouble due to the fouling of the motor is prevented. I have foundjthat much l'of the difliculty encountered in removing carbon from engine cylinmatter and impuriders is due. to the presence of mineral inatter drawnm With` the dust, such as silicon,

4which. cannot be removed by the oxygen burning methods, but can only be Yremoved by taking downthe 'engine and scraping With my attachment, Such deposits of e`x traneous matter are absolutely prevented.
